Application Abreviews Notes
  • Application notes
    ELISA: 1/20000.
    IHC-P: 1/50 - 1/100. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
    WB: 1/500 - 1/1000. Detects a band of approximately 102 kDa (predicted molecular weight: 102 kDa).

    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Function
      Location-regulated scaffolding protein connecting MEK to RAF. Promotes MEK and RAF phosphorylation and activity through assembly of an activated signaling complex. By itself, it has no demonstrated kinase activity.
    • Sequence similarities
      Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family.
      Contains 1 phorbol-ester/DAG-type zinc finger.
      Contains 1 protein kinase domain.
    • Post-translational
      Phosphorylated on Ser-309 and, to a higher extent, on Ser-404 by MARK3. Dephosphorylated on Ser-404 by PPP2CA. In resting cells, phosphorylated KSR1 is cytoplasmic and in stimulated cells, dephosphorylated KSR1 is membrane-associated.
    • Cellular localization
      Cytoplasm. Membrane. In unstimulated cells, where the phosphorylated form is bound to a 14-3-3 protein, sequestration in the cytoplasm occurs. Following growth factor treatment, the protein is free for membrane translocation, and it moves from the cytoplasm to the cell periphery.
